TOA 900 SERIES
PROGRAM TIMER
TT-104
DESCRIPTION
The TOA TT-104 is a program timer that comes in both
rack-mounted and tabletop models. When it is used in con-
junction with a spot announce machine, it can provide effec-
tive automatically timed announcements for schools,
factories and offices, etc. The TT-104 has 4 independent out-
put channels, with a program capacity of 30 steps per chan-
nel. Each channel can be programmed for a week, with
easily-made changes or cancellations. A channel assign-
ment function allows merging of 4 channels into one chan-
nel, for increased capacity. During vacations and special
holidays, a Pause Mode blocks transmission temporarily. An
Auto Off switch shuts the power off independently of output
channels. Output is no-voltage (dry) one-shot pulse contact.
In the event of a power outage, the clock time function and
stored programs can be maintained for approximately 100
hours by a back-up battery system.
